In today's new period of increasing industrial development, the application of new materials has become an unstoppable inevitable trend, a variety of industrial sites to expand the area, expand the scale, industrial upgrading, can not be separated from the role of the multilayer plate play. Multilayer plate as a new industrial materials, in the production of the status of the further enhancement of its as a high-density circuit board related materials, in terms of quality, price, production process is also different, the following small make-up to take you to understand the specifics of the price of multilayer plate.
Price of multilayer board
When multilayer boards were first made public by the gap method (Clearance?Hole), the incremental method (Build?Up), and the plating through method (PTH) three manufacturing methods. The gap-hole method is not practical because it is time-consuming to manufacture and is limited in densification. Layer method because of the manufacturing method is quite complex, plus the advantages of high-density, but because of the demand for high-density is not as urgent, has been silent; Er recently, due to the demand for high-density circuit boards, once again become the focus of research and development of various manufacturers. As for the PTH method, which is the same process as the double-sided board, it is still the mainstream manufacturing method for multilayer boards.

Multi-layer board manufacturing method
In the beginning, multi-layer boards were disclosed in the gap method (Clearance? Hole), the method of increasing the layer (Build? Up), the method of plating through the (PTH) three manufacturing methods. The gap-hole method is not practical because it is time-consuming to manufacture and is limited in densification. Layer method because of the manufacturing method is quite complex, plus the advantages of high-density, but because of the demand for high-density is not as urgent, has been silent; Er recently, due to the demand for high-density circuit boards, once again become the focus of research and development of various manufacturers. As for the PTH method, which is the same process as the double-sided boards, it is still the mainstream manufacturing method for multilayer boards.
Multilayer boards are generally manufactured with an inner graphic first, then printed and etched into a single or double-sided substrate and incorporated into a specified layer, then heated, pressurized and bonded, and then drilled with the same through-hole plating method as double-sided boards. These basic production methods have not changed much since the 1960s, but as materials and process technology (e.g., compression bonding technology, solution to the drilling of slag, film improvement) become more mature, the characteristics attached to the multilayer board are more diverse.
Multilayer development direction
With the progress of VLSI, miniaturization of electronic parts, high integration, multilayer boards with high-function circuits in the direction of the advancement of high-density lines, high wiring capacity of the demand is increasing, but also the electrical characteristics (such as the Crosstalk, impedance characteristics of the integration of the requirements of the more stringent. The prevalence of multi-legged parts and surface-mounted devices (SMD) has led to more complex shapes of circuit board patterns, smaller conductor lines and apertures, and a trend toward the development of high multilayer boards (10 to 15 layers). In the second half of the 1980s, in order to meet the demand for smaller, lighter weight high-density wiring, small holes, the trend of thin multilayer boards with a thickness of 0.4 to 0.6 mm is gradually gaining popularity. The hole guide and shape of the part are completed by punching. In addition, for some products that are produced in small quantities, the photographic method of forming patterns with photoresist is used.
Multi-layer basic use
Home decoration is mainly used in the veneer plywood, that is, in the factory has been very thin solid wood veneer pasted on the plywood. Veneer plywood is easy to use and cheaper than buying your own veneer and letting the construction team stick it.
Multi-layer board length and width specifications and construction template length and width specifications, basically: 1220 × 2440mm, while the thickness specifications are generally: 3, 5, 9, 12, 15, 18mm, and so on. The main tree species are: camphor, willow press, poplar, eucalyptus, etc..
Multi-layer boards have good structural strength and stability. With lightweight, high strength, good elasticity and toughness, resistance to shock and vibration, easy processing and finishing, insulation and other advantages, plywood glue content is large, the construction should be good edge treatment, day to reduce pollution.
Pick the difference between plywood
①Plywood has the difference between positive and negative. Selection, plywood should be clear wood grain, the front side is smooth and clean, not rough, to be flat and no stagnant feel.
②The plywood should not be broken, bruises, hard wounds, scars and other defects.
3 multilayer board without degumming phenomenon.
④ Some plywood is made of two different grain veneer pasted together, so in the selection of plywood should pay attention to the seam should be tight, no unevenness.
⑤ When selecting plywood, attention should be paid to the selection of plywood does not loose glue. If the hand knocking plywood parts, the sound is crisp, it proves that the quality is good, if the sound is muffled, it means that the plywood has been scattered glue phenomenon.
The above is what I share about the price of plywood related content, for the specifications are not equal, the quality of craftsmanship also have plywood, you can according to their own specific needs in different manufacturers to choose between. In the thickness, the use of resistance level, the size of the difference, in order to achieve the best results. Of course, the large-scale use of multi-layer board is also an important embodiment of the industrialization of the market and technological progress, I believe that the scale of our industry will be more rapid development. The above is what we share, I hope it will help you.
